PAPER-FEED DEVICE.

Specification of Letters Patent.

Patented J an. 23, 1917.

Application filed August 24, 1916. Serial No. 116,605.

T 0 all whom it may concern Be it known that I, linwann B. I'lnss, acitizen of theUnited States. residing in Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Paper-Feed Devices, of which the following is aspecification.

This invention relates particularly to devices for feeding writing orcarbon paper from a roll or other source of supply to the platen of atypewritlng machine, and the primary object of my invention is to earploy a stationary paper supply support, 4. 0., one not moving with thecarriage, and to associate therewith a guide for the paper which is soconstructed and operated as to prevent uneven feeding of the paper orundue strain thereon when the carriage is moved sidewise and during theline spacing operation with the carriage in different positions.

In carrying-out my invention I provide a guide for the paper as itpasses from the source of supply to the platen which is so constructedas to provide a looped or slack portion inthe web so that duringprinting the paper is supplied to the machine for a considerable timefrom this slack portion, and as soon as it is exhausted the guide isautomatically operated to pull another slack portion from the supply andthereafter the machine is fed from a slack portion as before.- In thisway the carriage may be moved sidewise and the paper fed for linespacing in any position of the carriage without such strain on any partof the paper as to produce irregularities in the alinement of theprinting on the paper. The preferred mechanism for accomplish ing theseresults is hereafter more fully described.

In the accompanying drawings:-Figure '1 shows a front elevation of atypewriting machine with paper feeding and guiding devices embodying myimprovements applied thereto. Fig. 2 shows a side elevation of the same.Fig. 3 is a detail view showing the relation of the paper cutter to thepaper. Fig. 4 is a perspective view of the paper guide.

The typewriting machine may be of any usual kind, a Royal Standardmachine being shown.

A indicates the platen and B a cross piece carried by links 6 pivoted tothe machine frame at I) and connected to springs I) which normally holdthe cross piece close to the platen and also serve .to hold the bar inits upward position when it is thrown upward and rearward.

, The roll of paper P is carried by arms 0 projecting forwardly fromstandards C, rising from the base I). The paper passes from the rollthrough a guide Gr and then to the platen A. The guide is carried bysupports 9 preferably in the form of Wires or rods attached to arms 6projecting rearwardly from the machine frame. The rods 1 are connectedat their, upper ends by a cross piece g which constitutes a fixed guidefor the paper web. A movable guide for the web consists of a bail gpivotally con- IlOCtQd with the upper ends of the rods {1 and having ahorizontally disposed cross piece across which the paper extends.Springs h connected to the bail near its inner end and to the supports 9by clips h tend to hold the bail in its lowermost position and to returnit thereto. The drawings show the paper web in three positions. The fulllines :12 indicate the position of the web when it is taut; the dottedlines y/ indicate the condition of the web when it is slack and thedotted lines 2. show its condition when the slack portion of the web isalmost exhausted.

lVhen printing, paper is drawn by the rotation of the platen from theslack portion of the web which gradually diminishes in size as the workprogresses, but by reason of the slack web the carriage may be movedfreely sidewise without undue strain 011 the paper and the paper may bemoved for line spacing without irregularities in the feed or in printingof the lines. When the paper assumes the condition shown at 2 the bailis raised from its lowered position to the position shown by full linesat g in Fig. 2, and as soon as it reaches this position, orsubstantially this position, the springs h react and pull the webdownward with a quick jerk causing the paper to uuroll and produceanother slack portion of the web. This operation occurs from time totime and the slack portion of the Web, possessing the adwantages beforedescribed is thus maintained.

The cross bar B is preferably formed with a knife edge is by means ofwhich the paper web may be cut. Fig. 2 shows the end of the paper at 7).By taking hold of this end of the paper and pulling it against the knifeedge while also pulling it forward and sidewise the paper can be raidilysevered. The cross bar B serves the double purpose of guiding andsevering the papc and may he raised and held out of operative positionwhenever desired.

\Vhile I have described one specilie way of carrying out my invention itwill be understood that my claims are not limited to the specificdevices illustrated.

I claim as my invention:

1. A paper feed device for the platen of a t vpewrit-ing machinecomprising a source of supply for the paper web. and a swingingspring-actuatel guide for the paper interpo.-rd between the platen andthe source oi supply for automatically producing a slack potion of tooweb between the source of supply and the platen while the paper is be-:5. A paper feed device for the platen of a tapewriting machinecomprising a source oli supply for the paper web, a guide over ply andlocated below the fixed guide for automatically producing a slackportion in the web between the source of supply and the platen. v

A paper feed device for the platen of a typewriting machine comprising astationary support for a roll ot paper, a fixed guide, another guideinterposed between the platen and the web support. and adapted to swingin a vertical plane. and a spring for swinging said last-mentioned guidedownward to produce a slack looped portion in the web between the rolland the platen when said guide is raised to a predetermined extent.

5. A paper feed device, con'iprisinga supvport for the web, a fixedguide, another guide adapted to swing in a vertical plane, and a springfor swinging said guide downward to produce a looped portion in the webwhen said guide is raised to a pl'talctermined extent.

6. A paper feed device, comprising a stationary support for a roll ofpaper and' a guide for the paper web, comprising a fixed portion overwhich the paper passes, a bail engaging the web and pivotedto move in avertical plane, and a spring tending to draw the bail downward and whichpulls saidv bail away from the roll when the bail is raised to apredetermined extent and the tension of the spring is sullieientlyincreased.

In testimony whereof, I have hereunto subscribed my name.
